Joubert argues the Minister provided "no evidence" to show that smoking cessation for a limited period would reverse or reduce the risk of contracting a more severe form of Covid-19, adding that she admits, in her court papers, that due to the "newness" of the disease, there is not enough data to assess whether or to what extent the chance of infection or disease progression decreases upon quitting smoking.

Citing Morjaria's expertise, the papers argue that there is "no consensus" in relation to smoking being a risk factor for Covid-19 risk progression – rather, currently available data suggests that risk factors for severe Covid-19 include older age, male gender, medical comorbidities including cardiovascular diseases, diabetes, hypertension, increased body mass index (BMI), chronic kidney disease, solid organ transplants and chronic pulmonary diseases.
